Wayan Vota gets to the core purpose of MOOCs, at least as I see them. "What we need to bear in mind is that the MOOCs are trying to make better quality education available to a great mass of people who are currently “non-consumers” of education and such quality is currently superior by far to whatever they may be getting right now. The MOOCs are not aimed to people who are willing to cheat but to those willing to learn." Good article, with an interesting comparison between MOOCs and OLPC.
